ABEL G-UIONNEAU, OF DENVER, COLORADO.

ORE-CONCENTRATOR.

Specification of Letters Patent.

Patented YOct. 1, 1907.

Application filed April 29, 1907. Serial No. 370,835.

To all 'whom it may concern:

Be it known that I, ABEL GUIONNEAU, a citizen of the United States,residing at Denver, in the county of Denver and State of Colorado, haveinvented new and useful Improvements in Ore-Concentrators, of which thefollowing is a specification.

This invention relates to ore concentrators, the object of the inventionbeingl to provide an effective apparatus of this character for quicklyconcentrating ores of different kinds supplied thereto. i

A concentrator involving v my invention possesses other advantageousfeatures which, with the foregoing, will be fully treated in thefollowing description of that form of embodiment of the apparatus whichI have selected for illustration in the accompanying drawings formingpart of this specification. The novelty of the invention will be coveredin the claims succeeding said description.

Referring to said drawings: Figure l is a top plan view of aconcentrator involving my invention, with a portion of the belt brokenaway. Fig. 2 is a rear elevation of the concentrator with the headmotion removed. Fig. 3 is a sectional side elevation of the same, thebelt being in section. Fig. 4 is a detail view in front elevation of thebelt. Fig. 5 is a top plan view of the same, and Fig'. G -is a'sectionaldetail of said belt. Figs. 7 and 8 are detail views of the adjustinggear.

Like characters refer to like parts throughout the several hgures.

The apparatus includes in its make-up a suitable bed or foundation andthis may be of any desirable character, the same comprising in thepresent instance the suitably connected duplicate sills 2 to theopposite ends of which are fastened in some convenient way the flexiblelinks or straps 3 of which there are four illustrated in the drawings.The upper ends of these links are connected in some desirable manner tothe connected frame members 4 which directly sustain the concentratingmechanism and which are simultaneously given a vibratory movement in adirection transverse of the endless belt hereinafter described for thepurpose of stratifying the pulp on said belt. The links 3 may be of woodor metal or a composition of these materials. The frame members 4 areseparated horizontally from the sills 2, as shown clearly in Fig. 2.

A roller or drum is shown at 5, andthe shaft 6 of said roller issupported by suitable bearings upon the frame members or beams 4, saidshaft 6 having fixed thereto at one end, as shown in Fig. 1, the disk 7having on its outer face a lug as 8, the function of which will behereinafter described.` This shaft G serves as a pivot or center for thebeams 9, said beams 9 having at the end thereof opposite the shaft 6bearings for the drum or roller 10 which is complemental to the drum 5.An endless belt as 1l travels around these two drums. The belt 11, or atleast the working portion thereof, is

inclined, and, in the present case, the upper run of said beltconstitutes the working portion thereof. The inclined belt may be madeof any suitable material. I prefer, however, to make it of rubber and,when of rubber, it will have molded thereon the transversely disposedriifles 12 which extend from the back of the belt or that part at theright in Fig. 3, to the front thereof. When the belt is of rubber Ipreferto make the riffles 12 of rubber, the said rifiies being ofprogressively decreasing thickness or depth from the back of the belt tothe front thereof. It is not essential, of course, that these parts beof rubber, as will be evident from what I have stated. Along the back ofthe belt I form a fiange as 13 which prevents the escape of pulp andwash water fromthe belt, the fiange extending the complete length ofsaid belt, as shown clearly in Fig. 4. I have shown by arrows in Figs. 1and 2 the direction of movement of the belt, and any suitable means maybe provided for operating the belt. I will hereinafter briefly describethe means shown for this purpose. The connected beams 9 are oscillatoryupon the shaft 6, this being for the purpose of angularly adjusting thebelt, and for varying this angular adjustment I may provide duplicatedevices acting against the respective beams 9, o'neof which will now bedescribed.

Upon the beam 4 shown in the foreground in Fig. 2 and carried by asuitable bearing thereon is a shaft as 14 having a cam as 15 operable byworm gearing denoted in a general way by 16, the worm of said gearingbeing carried on the shaft 17 rotatably supported by bearings upon saidbeam 4 illustrated in said Fig. 2. Said shaft l7 is equipped with a handwheel 18. By turning the two hand wheels, only one of which is seen, Ican, as will be clear, through the two cams 15 adjust the angularrelation of the two beams 9 and thereby the endless concentrating belt'll A worm gear is shown at 19, its shaft being supported by a bracketas 2() on the sill 2 shown in the foreground in said Fig. 2. Upon theinner side of this worm gear 19 is a lug 2l coperative with the lug 8hereinbefore described. A worm 22 on the shaft 23 meshes with the wormgear 19, said shaft 23 being supported by the bracket 20 and by abracket as 24 carried by the sill to which saidbracket 20 is fastened.On the shaft 23 is shown a pulley 25 connected by a belt 26 with thepulley 27 on the main shaft 2S of the head motion denoted in a generalway by 30. The head motion forms in itself no part of the invention, forwhich reason it is unnecessary to describe the same in detail. Any

suitable head motion may be employed so long as it gives to the endlessbelt an absolutely uniform accelorated forward stroke and a uniformlyretarded rearward stroke. The forward or concentrating stroke of thebelt, as will be clear, is transverse of the belt or in a directionextending from the back to the front of the i belt, or, in other words,from the right towards the left in Fig. 3. In addition to suchtransverse stroke of the belt, which is given to it by the so calledhead motion 30, it has a traveling movement which is effected in thepresent instance by the worm 22 and the worm gear I9, the worm receivingits motion from the shaft 28 through operative connections therewith.Owing to the two lugs 2l and 8 to which I have hereinbefore referred,there will always be an operative connection between the worm gear 2land the disk or wheel 7 so that, even while the belt is being vibratedor reciprocated through the head motion, it is also being simultaneouslygiven its feeding movement. The upper run of the belt Il is supported byseveral rollers as 3l carried by the connected beams 9. Owing to thepresence of these rollers 3l there is no possibility of the upper run ofthe belt sagging between the rollers or drums 5 and l0 respectively.

The pulp is supplied on to the concentrating belt in any way, forexample, by a feed box as S2 shown conventionally in Figs. 2 and 3 andlocated substantially centrally of the belt Il at the back thereof. lprovide two pipes as 33 at opposite sides of the feed box 32 forsupplying wash water, said pipes extending longitudinally of the belt atthe back thereof also as indicated in said Figs. 2 and 3. The pipes maybe supplied with the necessary wash water by pipes as Sli. I have shownthe wash water pipes 33 conventionally. The liquid slimes are dischargedover the highest end of the belt, while the tailings pass from off thelowest end of said belt, the heavier particles of the liquid slimespassing from the belt near the back thereof, while the heavier tailingsare discharged from the opposite end of the belt near the front thereof.The values are discharged froin the front of the belt and, for properlydirecting the saine therefrom, I provide a discharge apron'as 35 fittingunder the front portion of the belt between the rollers 5 and l0 andcarried by the forward beam 9, as shown clearly in Fig. 3. Under theupper inclined portion of the belt I] and between the sills 2 I preferto arrange a tank as 36 to receive the slimes which may adhere to thebelt after the drum l0 is passed and, for washing these adhering slimesfrom said belt, I provide a. wash water pipe as 37 which directs a jetor jets of water against the belt to separate therefrom any slimes whichmay adhere thereto, the slimes thus separated from the belt falling inthe tank 36 It will be assumed that the pulp contains galena, iron, andzinc. Of course, pulp of any suitable kind may be delivered in tothebelt, but I have selected for illustration pulp containing theseconstituents to indicate the action ofthe apparatus. The pulp issupplied to the central back portion of the belt Il from the feed box32. The vibratory motion given te the belt by the head motion stratifiesthe pulp or causes the mineral values to settle in the spaces betweenthe rifiies I2. The wash water is, of course, flowing and aids inkeeping the particles in suspension between the riiH es. Such washwater, however, is used primarily to wash the light or worthlessmaterial over said riflles l2, but has no direct effect in dischargingthe concentrates or mineral values over the front of the belt. Thedischarge of the concentrates is caused by the vibratory motion, thematerial on each forward stroke of the belt 'all at the extreme upperinclined end thereof.

being moved from the back or feed side toward the front side. As thevibratory stroke has the least effect on the heavier materials suchmaterials are discharged nearest the upper front side of the belt, whilethe lighter materials are discharged toward the lower front side of saidbelt. Galena would be discharged near the extreme upper end of the belt,while iron and zinc would be discharged lsuccessively over the frontside but between the gatlena and the lowest end of the belt. The quart/Jmixed with simili mineral values is discharged at the front of the beltnear the lowest end thereof and is subsequently crushed to separate themineral values therefrom and returned to the apparatus. lhe slimes stickmore or less to the belt and cannot be readily discharged therefrom.They are therefore carried up with the belt and fall from the same atthe highest point thereof. The slimes which are not thus separated fromthe belt are washed therefrom into the tank or box 3G by water from thepipe 37. ,lrhe heavier slimes are discharged from the belt near the backthereof, while the lighter slimes leave the belt near the iront thereof,but 'lhe tailings are discharged at the lowest end of the belt, thelighter tailings leaving the belt near the back, while the heaviertailings pass from the belt near the front thereof.

The beams or frame members Li, whether there be two or more, constitutea main vibratory frame while the connected beams t) constitute anauxiliary frame. The auxiliary frame vibrates with the main frame, butis also oscillatory with respect thereto so as to vary the angularrelation oi the e nnentrating belt.
